Abstract

The invention relates to an aircraft landing gear comprising a casing (401) in which a directable lower portion (402) is slidably mounted, and a directing member which is suitable for rotating the directable lower portion in response to a directing command. According to the invention, the directing device comprises an electrical motor (410) having at least one stator (411) and at least one rotor (413) which extend around the directable lower portion such that a rotational axis of the motor coincides with the swivel axis of the directable lower portion, the stator being secured to the casing and the rotor being rotatably secured to the directable lower portion.
